ELEVATO R.

SPECIFICATION forming part of Letters Patent No. 473,023.6, dated April19, 1892.

Application filed April 23, 1891. Serial No.390,182 (No model.)

To a/ZZ whom t may concern:

` Be itknown that 1, WILLIAM VEENscHoTEN, a citizen of the UnitedStates, residing at Hornellsville, in the county of Steuben and State ofNew York, have invented a new and useful Elevator, of which thefollowing is a specification.

`My invention relates to elevators, and has for its object to provide anelevator which may be used in private residences, stores, or otherplaces where it is not convenient to apply steam or other power tooperate the ordinary elevators now in use.

' In carrying my invention into practice I employ a double shaft, inwhich are arranged two cars hung upon a :rope or ropes in the usualmanner, which rope is connected to the top of one car and passes oversuitable sheaves or pulleys at the top of the double shaft, and isconnected to the top of the car in the other side of the shaft. In thismanner the cars are made to balance each other.

My invention further consists in a series of weights, which are housedin the space between the two cars, and in mechanism for connecting thesaid weights to either of the cars to balance a person who is ascendingor descending in the other car, and also in means.,A for preventingtheaccidental falling of they elevator, andy in means for permitting aperson to connect such a weight only as will exactly or very nearlybalance the weight of the person in the car.

The invention further consists of the mech-I anism illustrated in theaccompanying drawings, the peculiar construction, combination, andarrangement of which will be hereinafter fully described, and thepeculiar points of novelty particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a vertical sect-ional viewthrough an elevator shaft and cars constructed in accordance with myinvention, showing the several devices in their normal positions. Fig. 2is a vertical sectional view taken on the line z ,c of Fig. 1, lookingin the direction of the arrow. Fig. 3 is a similar view of a portion ofthe car, taken on the line y y of Fig. 1, looking in the direction ofthe arrow. Fig. 4 is a similar view taken on the line Q3 of Fig. 3,looking in the direction of the arrow. Fig. 5 is a horizontal sectionalview on the line w w of Fig. 3 with the false lar sliding bar indifferent positions. vis a detail perspective view of the angular latterare journaled sleeves or grooved pulleybottom removed. Fig. 6 isasectional view on the line 'U fu of Fig. 5. Figs. 7 and 8 are horizontalsectional views on the line w w of Fig. 3, looking upward and showingthe angu- Fig. 9

Fig. 12 is adetail sectional View of the upper part of theelevator-shaft, taken onthe line s s of Fig. 11. Fi 13 is a similar view on the line r r of Fig.I1. Fig. 14 is an elevation of one of the weightsV and the track uponwhich it is supported. Fig. 15 is a longitudinal sectional view of amodified form of weight. Fig. 16 is a detail perspectivel view of oneendof one of the operatinglevers.

Similar numerals and letters of reference designate corresponding partsin the several views.

Referring now more particularly to Fig. 1, .it will be seen that myinvention consists of an elevator-shaft divided vertically into twoparts A and B, in each of which a car 1 and 2,1respectively,is arrangedto pass up and down. At the top of the shaft two pairs of parallel beams3 and 4 are arranged atright angles to each other, the lower pair 3serving as central supports to the upper pair 4, upon which wheels 5,one of which is situated over each .of the parts A and B of the shaft. Arope 6 of wire or other suitable material is connected at its ends tothe tops of the cars 1 and 2 and passes over the wheels 5, thussuspending the two cars in the opposite sides of the shaft, so that theywill balance each other, and when one descends the otherY will ascend.

The elevator-shaft is divided by two vertical beams 7, which in practicewill be made` about nine inches wide. These beams are placed centrallyin the shaft'at the front and back thereof, and the inner sides of thecars slide against their edges. In the space loetween the two beams 7and centrally between the cars are arranged vertical beams 8, whichstand at suitable distances apart and are of such width as to occupyabout one-third of the space between the opposing sidesof the IOO cars.Upon one side of each of the beams 8 are secured brackets 9, whichterminate in rails 10, upon which the weights 11 12 13 are supported,and the position of the said rails 10 is such as to be about midway ofthe height of the cars when standing at their upper and lower positions,as shown in Fig. 1. Extending from the sides of the lcars at aboutmidway of their height are rails 14, corresponding in shape, size, andnumber with the rails 10 and in such position as to come opposite theends of the said rails 10 and form continuations thereof when the carsare standing in their normal positions. The weights 11 12 13 are oblongand pointed at their ends and are provided about midway of their -lengthwith recesses 15, which extend through from side to side of theweightand have anti-friction rollers '16 journaled in their. upper parts,which roll upon the tops ofthe rails 10. The rails may be grooved toreceive the rollers 16, if desirable. Two similar levers 17 18 arepivoted to each of the beams 8 at the points 19 at equal distances aboveand below the central point between the upper and lower rails l0, andthe short arms 2O of the levers 17 18 are pivoted together, as at 21,thus forming a compound lever, the pivot working in a slot in one of thelevers, so that when the lower end of the lower lever is pushed to oneside the upper end of the upper lever will move a corre. spendingdistance to the same side, as shown The upper and lower ends of thecompound lever 17 18 extend above and below the rails 10, and theirendsy are formed, as shown in Fig.16, with a lug or,

in dotted lines in Fig.l.-

`arm'22, proj ectingi'nwardly from the edgesvto embraceone of theweights. Thus by moving one end of one of the levers, as 17, sidewisethe weight embraced by the arms ofthe lever 18, connected thereto, canbe rolled ott the rail l0.

Through the sides of thev cars, next to the beams 8, pass the angularslidingbars 23, (more clearly shown in Fig. 9,) which are arranged toslide in suitable guides 24. These angular sliding bars 23 areright-angular in cross-section, and when in operative position one side,

` opposite to the compound levers 17 18, and

when they are pushed outwardly they will pushV the end of the lever withwhich they come in contact away from -thecan A sliding bar 32 isarrangedin suitable supports 33 just below the cut-away portion 27, butin the path of the shoulder 28 upon the vertical side of the angular bar23, and is provided with a `series of notches 34 along its upper edge,

which when the bar is moved in thedirection of the arrow a will passunder the vertical sides ofthe sliding bars 23 to allow the shoulders 28to pass therethrough. The notches 34 are arranged at such distancesapart that only one of the notches can be in position to allow ashoulder 2810 pass through at a time, and when in its normal position,as shown in Fig. 3, the bar 32 will prevent any of the angular slidingbars 23 frombeing pushed outwardly against the levers. i

In the bottom of each car is arranged a series of levers consisting oftwo parallel levers 35, placed centrally across the car and pivoted in abracket 36, projecting upwardly from the bottom of the carnear the outerside thereof. The levers 35 are connected together and held at asuitable distance apart by rods 37, 38, 39, and 40, the rod 37 extendingthrough the levers into the bracket 36 and forming the fulcrum. The rod38 extends through the ends of the short arms of the levers `35 and haspivoted upon its ends a pair of levers 41, the opposite ends of whichare pivoted in the opposite or inner corners of the car, as at 42, Fig.5. Two shorter levers 43 are pivoted in the' outer corners 44 ot' thecar and have their opposite ends pivoted to the centers of the levers4l, as at 45. Studs 46 project upwardly from the levers '41 and 43, uponwhich the false bottom 47 is supported. From this construction it willbe understood that if a person steps upon the false bottom 47 thetendency will be to depress the short arms of the levers 35 and elevatetheir longer arms.

A series of weights 48 49 50 of unequal weight are arranged between thelevers 35 upon the rod 39 near the, ends of the long arms of the saidlevers. rIhese weights are of different sizes, as shown in Fig. 3, andhave slots 51, through which the rod 39 passes, the slot 51 in thesmallest weight being of such length `that the weight will rest uponthe-bottom of the car and also in, contact with the rod 39, to be raisedthereby at its first upward movement. The slot 5l in the next sizeweight is longer, so that it will be lifted by the rod 39 after it hasraised the smallest weight a short distance, and the slot in the nextweight is still longer, and so on to the end of the series.

VThe weights are of such weight that should a light person step in thecar the smallest weight will be raised, and they are so graduated thatthe heavier the person is the more `weights will be raised, thus raisingthe long arms of the levers 35 a distance determined by the weight ofthe person in the car. Upon the car below the sliding bar 32 and havingits vertical arm connected with the said bar 32, ias at 54. Thus whenthe rod 52 is raised by lthe lever 35 it will turn the bell-crank lever'53 and slide the lbar 32 a distance correspond- IOO ITO

ing to the movement of the levers 35, which latter is determined by theweight of the person in the car.A The notches 34 in the bar 32 are soplaced that when a light person steps in the oar the movement of the bar32 will be sufficient to move one of the notches in line with thesl1oulder28 upon one of the angular sliding bars 23, thus allowing thatbar to bel moved outwardly, but preventing any of the others frommoving. Should a heavier person step into the car, the bar will be moveda little farther, thus bringing another notch 34 in line with the nextangular bar 23, but moving the first notch out of line with the lirstbar23 and permitting the second bar 23 only to be operated. The purpose ofthis will. be explained farther on. To enable a person to operate thesliding bars 23,a lever 55 is fulcrumed in a bracket 56 over each of thesaid bars 23 and hangs through a slot 57 in the guides 24 against theinner end of the angular bar 23, the lower end of said lever terminatingin a handle 58, by means of which the bars 23 may be moved outwardly,'aswill be readily understood. The angular bars 23 are returned to theirnormal position by means of a spring 59, (better shown in Figs.7 and 3,)which-is arranged within the angle formed by the sides 25 and 2G of thebar and connected at one end to a lug 60 in the inner end of the saidbar and atits other end to the side of the car. The tension of thespring is such that it will hold the sliding bars 23 in their normalpositions, as shown in Fig. 7, returning them by expansion from anoutward position and by contraction from an inward position. Above theangular bars 23 is arranged a sliding bar 61, supported in suitablebrackets 62 and provided with downwardlyprojecting lugs 63,corresponding in number and position with the angular bars 23 andarranged to rest against the edges of the horizontal sides 25 of thesaid angular bars. When the angular bars 23 are in their normalpositions, the lugs G3 rest against the cut-away portion 29 of theangular bars, and when one of these bars is moved inwardly or outwardlythe inclined surface 30 or 31'will come in contact with one of the lugs63 and slide the bar G1 in the direction of the arrow b. A belloranklever G5 is pivoted above one-end of the sliding bar 61, and thevertical arm thereof is connected with the said sliding bar, as at 66.To the horizontal arm of the bell-crank lever 65 is pivoted a rod 67,which extendsdownwardly and is pivoted at its lower end to thehorizontal arm of a bell-crank lever 63, pivoted to one side of the carnear the bottom thereof. The vertical arm of the bell-crank lever G8depends nearly to the bottom of the car and has pivoted to the lower endthereof a rod 69, which extends toward the opposite side-of the car andis connected with the inner end of a spring-actuated bolt 70, whichprojects through the side of the car, as shown in Fig. 6. A similarspring-actuated bolt 71 is arranged in the opposite side of the oar toupper doors are shown.

project through the same side as the bolt 70, (see Fig. 5,) and to theinner ends of each of the bolts 7 0 and 71 are pivoted levers 72 and 73,respectively, each of which levers extends toward the other till theymeet and are pivoted together, as at'74, midway between the Y ends ofthe bolts and 71. The levers 72 and 73 are fulcrumed to the bottom ofthev car at equal distances upon each .side of the pivotal point 74, asat 75. Thus when one of the bolts-say 7 O-isdrawn inwardlythelevers 72andV 73 will be moved into the position shown in dotted lines in Fig. 5and will draw the other bolt 71 inwardly a corresponding distance.

From the foregoing description, takenin connection with Figs. 3, 5,and-6 of the drawings, it will be understood that when the sliding barG1 is moved in the direction of the arrow b itwill, through thebell-crank levers 65 and 63 and the rods 67 and 69, draw the bolt 70inwardly, and,through thelevers 72 and 73, actuate the bolt 71 in thesame manner. l 'lVhen the angular bar 23 resumes itsnormal position, thesprings 76 upon the bolts 70 and 7l will return the bolts, and, throughthe aforesaid connections, the sliding bar 61 to their normal positions.l

When the elevator is operated, as will be hereinafter explained, one'ofthe weights 1l, 12, `or 13 is moved from its rail 10 onto the adjacentral 14 on one of the cars, and in order to return the weight so moved toits normal position a pair of oblong frames 77 is arranged to inclosethe beams 8, the weights 11, 12, 13, and the compound levers17 and 18 attheir upper and lower extremities. These oblong frames 77 are arrangedbetween the front and back beams 7 7 to slide upon guides 73. They aremade about two-'thirds of the width between the two cars, or wide enoughto allow one of the said levers and weights to move to one side withinthe said frames, while the others remain in their normal position.

ICO

Thus should one of the compound levers 17 Y.

13 be in the position shown in dotted lines in Fig. 1 the frames 77 willoccupy the position in which the upper one is shown in said figure. Nowif one of the frames be moved into the position in which the lower frameis shown it `will be obvious that it will bring the compound lever 17 18to a vertical position, and thus move the corresponding weight to itsnormal position. As this should be done every time a person leaves thecar, I have arranged mechanism in connection with the door by means ofwhichl the weights will be moved to their normal position when the dooris opened. This'mechanism will now be described. i

The doors SO are hung upon a facing-piece 81, secured upon the face ofthe front beam 7, as shown in Figs. 1 0 and 11, in which the two Throughthe beam 7 and facing-piece 81 are formed slots 82, in which are pivotedlevers 83, the long arms of whichextend into short slots in the frontend inner edges of the doors 80. Upon the doors are lugs 86, havingtheir outer surfaces inwardly curved and in proper position to impingeagainst the ends of the rods 84 when one of the doors isopened,and thusmove the short arm of the lever'83 away from the said door, turning theleverinto the position shown in dotted lines in Fig.11 and moving oneend of the oblong frame 77 toward the car on the side of the shaft wherethe door was opened. In order to prevent binding, it is necessary thatboth ends of the frame 77 be moved simultaneously, and to accomplishthis a T-lever 87 is pivoted in a recess 88 in the beam 7 at the rear ofthe elevator-shaft. The arm 89 of said T-lever extends downwardly and ispivoted in a slot 90 in the rear end ofthe oblong frame 77. The twohorizontal arms of the T- lever 4extend into the opposite sides of theelevator-shaft and are connected by rods 9l with bell-crank levers 92 inthe upper rear part of the shaft. The bell-crank levers 92 are connectedby rods 93 with bell-crank levers 94 in the front part of the shaft,which latter are in turn connected by link-rods 95 with opposite ends ofthe horizontal arm of a T-lever 96, pivoted upon the facing-piece 81. Tothe depending arm of the T-lever 96 are pivoted two rods 97, whichextend horizontally in opposite directions through guides 98 upon thefacing-piece 8l and terminate in` proper position to be operated uponbythe lugs 99, which aresimilar to the lugs 86 and act upon the rods..97in the same mannerthat the last-named lugs act upon the rods 84.

From the foregoing it will be understood that when one of the doors isopened the lugs 86 and 99 will impinge against the rods 84 and 97 onthat side of the facing-piece 81 and will move the lever 82 to slide thefront end Aof the frame toward the door which is being connection, withthe lower doors to operate the lower frame 77; but in this instance thedevices will be invertedto bring them below instead of above theoperating parts, as shown.

in Figs. 1 and 2. The hinges 100 may be placed at the base of the lugs86and 99 to strengthen the door at these points, as shown in Fig. 10.

To prevent the weights 11 12 13 from being moved off of the rails 10when there is no carin position to receive them, I provide the plates101, pivoted between the edges of the front and rear beams 7 just beyondthe upper and the distance the sliding bar 32 will move.

lower ends of the compound levers 17 18, the upper pair being pivoted sothat when in a horizontal position their outer edges will be heavierthan their inner edges. Pins 102 are placed in the beams 7 just abovethe inner sides of the upper pair of plates 101, against which thesesides rest when the said plates are in their normal horizontal position,the heavier outer edges of the plates keeping them in this position, asshown at e' in Fig. 1. By inspection of the figure it will be seen thatwhile the plates 101 are in a horizontal position the weights cannot bemoved off of the rails 410 on that side of the shaft. When the car comesup, it will lift the outer heavy edge of the plate 101, thus turning theplate to a vertical position out of the way of the weights, as shown atd in Fig. 1. The plates 101 in the lower part of the shaft operate inthe same manner, except thatthey are heavier at their inner edges andrest upon the pins 102. Thus (shown in Fig. 11,) having an'inwardly-pro7 jecting lug 106, which is in position to be engaged byinclined surfaces upon a plate or lug 107, secured in proper positionupon the front of the car, and be withdrawn thereby when the car arrivesat its stopping place, as will be readily understood. spring may be usedto close the door.

The operation of the invention is as follows: When in their normalposi-tion, one of the cars is at the top and the other at the bottom ofthe shaft, and they are held in this position by the bolts 70 and 7l,which take into recesses 108 in the sides of the shaft, as shown inFig. 1. The weights 11 12 13 are supported upon their respective rails10, and the rails 14 of the cars are in position to receive the weighttherefrom. If a person wishes to ascend, he steps into the lower car. Assoon as his weight is upon the false bottom 47 thereof it .will causethelevers 35 to raise one or lnore of the weights 48 49 50, thusdetermining the distance the levers 35 will rise, and consequently Forinstance, should a light person enter the car the lighter weight onlywould be raised, thus causing the levers to move far enough to bring therst notch 34 in the bar 32 under its re- IOC Any suitable K IIO spectiveangular bar 23, allowing that bar 1 only to be moved. Should a heavierperson enter the car, two or more weights will be raised, thus movingthe lever a greater distance and causing the second or third notch 34 tomove under its respective bar 23, thus allowing the second or third bar23 to be moved. The weights 11 12 13 are arranged so that the compoundlever 17 18, embracing the lightest weight 11, will be opposite to thebar 23, which is released by the weight of a light person, and the nextheavier weight 12 will have its compound lever opposite to next bar 23,and so on to the end of the series, which may consist of any number ofweights and sliding bars 23. From this explanation it will be understoodthat the sliding bar 23, which 1s released by the weight of the personin the car, will be opposite to the compound lever 17 18, which embracesa weight corresponding, or nearly so, to the weight of the person. Theperson notes which of the bars 23 is released, and by means of the lever55 over said bar pushes that bar outwardly. This will force the lowerlever 18 of the pair away from the lower car and bring the compoundlever and the weight embraced thereby into the position shown in dottedlines in Fig. 1, rolling the weight over upon the rail 14 of theopposite car and carrying both of the frames 77 over to that side. Thiswill place suicient weight upon the upper car to balance, or nearly so,the person in the lower car. When the sliding bar 23 is moved outwardly,it will slide the bar 61, as has been hereinbefore explained, andwithdraw the bolts and 71, and the lever and weight moving against theother car will move one of the sliding barsV 23 of that car inwardly,which movement will alsoactuate the bar 61 to withdraw the bolts 70 and71 of that car, thus releasing the two cars. The person wishing toascend grasps the rod 103 and by pulling thereon causes the car in whichhe is to ascend, while the other descends, the cars being so nearlybalanced by each other that only a slight effort is required to raise orlower them. The length of the rope '6 must be` such that when one carrests upon the air-cushion 104 the other one will stop at the upperfloor. As soon as the car has started to move the lever 55 may bereleased, and the spring 59 in the sliding bar 23 will return the saidbar to its normal position, thus allowing the bolts 70 and 7l to springoutwardly and slide along the inner sides of the shaft until the carsarrive at the end of their movement, when they will take into theirrespective recesses 108 and hold the cars, as before. As the cars cometo a stop the plates 107 will withdraw the spring-latch 105 and allowthe door to be opened, and when this takes place the corresponding frame77 will be moved to that side of the shaft and return the weight to oneof the rails 10 in the lower part of the shaft, leaving the elevator inposition for the person to descend or for another person of differentweight to ascend. When the person wishes to descend, the weight is inthe lower part of the shaft, and by operating the lever 55 he moves theweight onto the other car and releases the cars as before, then graspingthe rod 103 lowers the car he is in to the bottom of the shaft, when thesame operations will take place to secure the cars in their positionsand return the weight to its normal position.

Although only three of the weights 11 12v 13 are shown and described, itwill be obvious that any number that can be accommodated between thefront and rear beams 7 7 may be used, and they may be graduated to suitthe persons most liable to use the elevator. By

having the weights to differ about twenty or twenty-live pounds they maybe arranged to -It is formed in two parts, the main or lower part 110having a spindle 111 projecting upwardly from the center thereof and thecap for upper part 112 being recessed longitudinally to receive thespindle 111, by which it is heldin place. When it is desired to increasethe weight, the cap 112 is removed and fone or more weights 113 114 115,which are made to fit upon the spindle, maybe placed thereon, afterwhich the cap is returned to its place.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-
